In India at some universities if you do so and your students are members of some mafia gang, they will kidnap you and give you a good beating. I know many professors at those type of colleges who go underground after releasing the grades :-)

The question is, who should you fail: the out-of-control, insensitive-to-world-hunger students who threw pies at you, or the cowardly student who did not? Or perhaps you should fail students randomly, just to keep them on your toes. I am fortunate not to have anyone likely to throw a pie at me, and I'm not planning to visit Pittsburgh until this comment thread is long forgotten.

I'm reminded of the MIT tradition of professors competing to win the Big Screw. They wouldn't just talk about failing students; they actually do things like give calculus lectures in French, covering material that would be included on the final exams.

Luis, if you're trying to turn CMU into MIT, you'll have to crank up the evil a bit. :-)

It absurd, contradictory, almost bizzare that a PROFESSOR says he wants to FAIL more students. It implies wanting more stupide people. Or unknowing any other motivation toward studying different from a animal-avoid-pain fear technic.

The ideal (not attainalbe but orientative) is a professor who doesn't have to fail ANY student due to his great job.
